The controller 110 of the cooking apparatus 100 may determine whether to automatically cook according to a control command input from a user through the user interface 120 . For example, when the user puts food into the cooking chamber and inputs an automatic cooking start command through the user interface 120 , the controller 110 starts automatic cooking.

When it is determined that automatic cooking is performed (YES in S1010), the cooking apparatus 100 detects the weight of the food (S1020).

The control unit 110 of the cooking apparatus 100 may detect the weight of the food accommodated in the cooking chamber based on the electrical signal output by the weight sensor 135 .

Specifically, the control unit 110 controls the cooking chamber based on the frequencies of the electrical signals output by the plurality of crystal oscillator microbalances 131-1, 131-2, 131-3, and 131-4 included in the gas sensor 131 . It is possible to determine the type and concentration of the gas inside.

For example, the controller 110 may determine the presence and concentration of hydrogen sulfide based on the frequency of the electrical signal output from the first crystal microbalance 131-1, and the second crystal microbalance 131- The presence and concentration of ethylene can be determined based on the frequency of the electrical signal output by 2).

For example, the controller 110 may determine whether the food is meat, fish, vegetables, fruit, processed dairy food, fermented food, or the like.

The food generates gases of different types and concentrations according to the type of the food.

For example, as shown in FIG. 6, kimchi contains approximately 0.1 [ppm] (parts per million) of acetic acid, approximately 23 [ppm] of aldehyde, approximately 95 [ppm] of sulfur compounds, and approximately 180 [ppm] ] of alcohol.

In addition, as shown in FIG. 7 , meat generates about 0.03 [ppm] of sulfur compounds and about 0.03 [ppm] of volatile organic compounds.

In addition, as shown in FIG. 8, the fruit generates approximately 6.1 [ppm] of ethylene and approximately 43 [ppm] of volatile organic compounds.

As such, since the type and concentration of gas generated according to the type of food are different, the controller 110 may determine the type of food according to the type and concentration of the generated gas.
